Answer:
Option I
Step-by-step explanation:
Given that for families who live in apartments the scatterplot of the family’s income and the amount of rent they pay is approximately linear with a correlation of r = 0.60.
This implies that there is a positive association between income and rent paid.
Also since r is greater than 0.5, we can say that there is a moderately strong correlation.
All these can be interpreted as if income goes high, rent also would be higher.
The rise in rent due to income would be 0.6^2 =36% only
The regression line need not pass through 60% of income rent data points but it passes through average of the data points.
Hence only option I is right.
Answer:
The sixth number in series is 13.
Step-by-step explanation:
Given series : 3, -6, 12, 4, 20, ?
The pattern followed by the series is:
The first number = 3
Second number = 3 - 9 = - 6
Third number = - 6 + (9 ×2) = -6 + 18 = 12
Fourth number = 12 - 8 = 4
Fifth number = 4 + (8 ×2) = 20
Sixth number = 20 - 7 = 13
Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.
So as per the above pattern, the sixth number in the series is 13.
